IF he's like me, he has a 4-button comfort control and a control box.
You'll need to tell us what you've got in there now... There are a ton of possible combinations.

The install docs for your unit are generic across several, but they're available here:
http://bryantrv.com/docs2/docs/opera...air.pdfControl box instructions are separate, but on the underside of your unit you can see compatible systems listed. If you need an analog control and a an interior dial-control, I've got a brand new one that I'm not going to use with a a ducted system.

The instructions for hooking to the A/C and Furnace should be in the box with the Thermostat.

You will need to identify the wires from teh A/C. They should be common, Cool, Fan low and Fan high. These hook to the same screws on the T-stat. Again this should be explained in the thermostat manual.

The two wires from teh furnace hook to the furnace screws on the T-Stat. in theory it matters not which goes where but if it is an electronic T-Stat it might so again check the T-Stat manual.> That is where you will find the info you need.
Home is where I park it!

Furnace connections (2 blue wires) will be up at the roof unit. You will need to swap the old control box or purchase a new one to match the analog T'stat.
